To make the crab cakes, in a large bowl, whisk together the mayonnaise, egg, Old Bay seasoning, Siracha sauce, chives, and parsley until well combined. Add the crabmeat and fold in gently with a rubber spatula. Sprinkle ½ cup of the panko over the mixture, and fold in gently, taking care not to break up the crabmeat. Cover with plastic wrap and refrigerate for 10 minutes. Remove from the refrigerator and fold in the remaining ½ cup panko. Season with the salt and pepper. Cover tightly with plastic wrap and refrigerate for at least 3 hours or up to 12 hours.
Meanwhile, make the Lemon Dill Sauce.
Combine all of the ingredients in a bowl and stir well. Refrigerate until chilled. The sauce will thicken as it chills.
Divide the crabmeat mixture into 8 equal portions. Carefully form each portion into a barrel-shaped cake about 2-1/2 inches in diameter and 1-1/4 inches tall.
Preheat the oven to 450 degrees.
Place the crab cakes on a parchment lined baking sheet, being careful they don’t touch one another. Brush the tops of the cakes with the remaining butter.
Roast the crab cakes undisturbed until the undersides are golden brown, about 10 minutes, or until the tops are golden brown and the crab cakes are firm to the touch.
Place a nice amount of the lightly dressed salad on each of six plates and top witj a warm crab cake ~ place a spoonful of the Lemon Dill Sauce on the crab cake and serve immediately.
For the Salad:
In a small bowl, whisk together the lemon juice, honey, shallot olive oil, salt and pepper. Taste for seasoning.
Combine the salad ingredients in a large salad bowl and lightly dress the salad just before service.
